Abstract:

In order to compare the difference between primary forest and rubber plantation after land use changed, the author took common termite species in Xishuangbanna as example to study the seasonal changes of methane and carbon dioxide. In this study, the Xishuangbanna region of the common termite species Macrotermes soil ridge, for example, the seasonal changes of methane and carbon dioxide, methane and carbon dioxide emissions in the rainy season was 3.5 times than the dry season. A large area of rubber plantations in Xishuangbanna region caused by land use change, caused the greenhouse effect. From insects to land use change on greenhouse response point of view to explain the increase in greenhouse gas emissions after land use change had accelerated global warming. The study ignored the seasonal variation of the release of methane and carbon dioxide in termite heap materials. The results showed that seasonal changes in the termite population may lead to the seasonal changes of the termite heap of methane and carbon dioxide emissions factors. This result required a combination of the termite mound gas emissions and removal of other factors that affected the termite heap gas emissions to be proved.
